MACHINE FOR THE MANUFACTURE OF TAPE BY A WINDING METHOD This invention relates to the manufacture of tape; more particularly. to the manufacture of tape by a winding method rather than by knitting or weaving; still more particularly, to a machine for the manufacture of tape by the hereindescribed winding method.

The manufacture of tape is a highly competitive business as is well known by those experienced in the art. Many different ways of manufacture of tape have been suggested, and some even tried, with varying degrees of success.

it is the principal object of this invention to provide a machine for the manufacture of tape by a winding method that is both efficient and economical.

Another object of this invention is to provide a machine for the manufacture of tape by a winding method that embodies a minimum number of parts requiring a minimum amount of maintenance as well as attention during the running of the machine.

Still another object of this invention is to provide a machine for the manufacture of tape by a winding method that can produce tape from cotton thread, fiberglas, plastic. or any other material in thread form and an adhesive bonding material, such as glue or the like, without the necessity of changing any of the parts of the machine.

Other and further objects and advantages of this invention will no doubt come to mind as the reading of this specification and its appended claimsproceeds and the accompanying drawings are examined in connection therewith.

In the drawings:

FIG. 1 is a pictorial view of the major parts of this invention in the process of manufacturing tape.

FIG. 2 is a side view of FIG. 1, additional parts of this invention are shown in FIG. 2.

FIG. 3 is a sectional view of a part of this invention, taken substantially along line 33 of FIG. 1, and viewed in the direction indicated by the arrows.

In the several views of the accompanying drawings like parts of this invention are indicated by like reference numbers.

The framework supporting the parts of this invention herein illustrated in the accompanying drawings is not shown for reasons of clarity and as many parts of the drawing as is possible are not illustrated for the same reason.

Directing one's attention first to FIG. 1 of the accompanying drawings it will be seen that this novel invention consists of a cylindrical part, which I call the body 5 and which is mounted vertically on a centrally located shaft 6 which is supported by the disk 7 in the thrust support 8 whose tubular shaft 9 is supported by the ball bearings 10. A pulley ii is secured to the aforesaid tubular shaft 9 between the two aforesaid ball bearings 10. A belt 12 encompasses the just-mentioned pulley 11 as well as the pulley 13 that is located on the lower end of the shaft of the electric motor 14. The electric motor is shown only in FIG. 2 of the drawings. An L-shaped tube 15 extends outward and downward from the aforesaid tubular shaft 9 to a predetermined position outward from the side and top of the aforesaid body 5. The yarn 16 passes through the aforesaid tubular shaft 9 and the L-shaped tube 15, as can be seen clearly on examination of H08. 1 and 2 of the drawmgs.

Continuing to look at FIG. 1 of the accompanying drawings it will be seen that this invention also embodies two opposed vertical endless rubber belt conveyors 17 that are mounted in the periphery of the aforesaid body 5. The conveyors, which are narrow in width, are driven by the longitudinally disposed cylinders 18. Tw opposed pressing rollers 19 and 20 are so mounted at right angle to, and below the aforesaid cylinders 18 as to press the paper 21 on the top of which is located a heat sensitive glue and the straight threads 22 which are coated with heat sensitive glue. Two opposed securing rollers 23 are located at a predetermined distance below the aforesaid pressing rollers 19 and 20 of this invention.

It will be noted on examination of FIG. 2 of the drawings that in this illustration of the invention certain modifications in the configuration of the structure of the machine have been made from that machine shown in the aforesaid FIG. 1 of the drawings. These differences in structure are so well known and understood by those experienced in the art that no explanation of the same is considered necessary in this specification and its appended claims.

The way in which this novel invention works is selfexplanatory to those experienced in the art when examination of the accompanying drawings is made. However, for the benefit of those less experienced in the art, the following statement is now given.

When one is ready to manufacture tape by means of this novel invention, the aforesaid yarn 16 is fed down through the aforesaid tubular shaft 9 and the L-shaped tube 15 and then placed on the side of the aforesaid body 5. Here it is held by one of the aforesaid rubber belt conveyors 17. The aforesaid yarn 16 is continued to be wrapped around the aforesaid body 5 by.the activation of the aforesaid electric motor 14. At the same time the aforesaid conveyors 17 are activated.

The already-mentioned paper 21, having the alreadynoted heat sensitive glue on the top thereof, is fed over the aforesaid roller 19, down against the side of the aforesaid body 5, and against the aforesaid yarn 16 that is being wrapped around the body by means of the two aforesaid rubber belt conveyors 17. At the same time this operation is being performed, the aforesaid straight threads, which are coated with heat sensitive glue, are being fed into the often-mentioned body 5 by means of the previously-mentioned roller 20. The finished tape 24 is now formed, as will be understood by those experienced in the art, and it comes out between the two rollers 23 of this invention.

This invention is subject to any and all changes detail design and or modifications that one may care to make in so long as the changes and or modifications all fall within the scope and intent of the appended claims.
